btrfs: open via dedicated fs bdev helpers
Route the device opens through fs_bdev_file_open_by_path() so each device
is registered against the superblock, and convert the matching releases
to fs_bdev_file_release().
The temporary identification opens that only read the superblock and
close again pass a NULL holder and keep using bdev_fput().
On the close path the superblock is taken from bdev_file->private_data
(the holder set at open) rather than device->fs_info->sb: a mount that
fails before btrfs_init_devices_late() runs leaves device->fs_info NULL,
which close_fs_devices() would otherwise dereference.
